Removal of non-conductive hydrophilic coatings from lands of fuel cell bipolar plates |
摘要 |
A bipolar plate for a fuel cell is provided including a plate having an active surface with a plurality of flow channels formed therein. The plurality of flow channels have a hydrophilic coating deposited thereon and define a plurality of lands disposed therebetween. The plurality of lands is substantially free of the hydrophilic coating. Furthermore, a thickness of the hydrophilic coating is substantially constant along a length of the active surface and an edge of the hydrophilic coating adjacent the plurality of lands is substantially continuous. A method for preparing the bipolar plate is also provided.
